E-E-A-T Quality Commitment
Stringent 4-Tier Quality Control SOP
Yiwu PAVI Technology Co., Ltd. operates with a documented QA system tailored to the expectations of B2B distributors in North America, Europe, and Asia-Pacific.
01
IQC: Incoming Inspection
Chemical composition validation of aluminum alloys, tensile verification of nylon cords, and surface inspection of raw polymers before entering assembly lines.
02
IPQC: In-Process Control
Real-time machine monitoring during drilling, manual pressing, and folding operations. Tolerances are re-checked every 500 units with calibrated height gauges.
03
FQC: Functional Testing
100% operational verification: electrical pumps pass auto-stop pressure checks; tail lights undergo IPX6 water spray exposure; locks face anti-shear tests.
04
OQC: Outgoing Audit
AQL 2.5/4.0 standard carton drops, packaging barcode scannability verification, pallet wrap inspection, and container moisture protection checks before dispatch.
